Lithium Batteries – Lithium Secondary Batteries – Li-ion Battery | Ionic Liquid Electrolytes

Lithium-ion battery technology poses safety issues due to the inherent incompatibility and flammability of the organic solvent-based liquid electrolytes. Ionic liquids have emerged as ideal materials that can supersede such solvents due to their unique physicochemical properties and propensity for rational design; they are integral for the development of lithium-ion batteries with superior safety, lifetime and performance. In this chapter, we present the recent advances of ionic liquid electrolytes for lithium-ion batteries outlining their functional structure, physicochemical properties and use case for post-lithium batteries. Lastly, we provide an outlook for the optimization of ionic liquid-based electrolytes utilizing computational models, machine learning methods and advanced operando experiments.
